Study Summary
This study will examine the underlying mental processes that determine how people understand social behavior, remember information, and think. Language, planning, problem solving, reasoning, social behavior, and memory are the critical parts of cognition that make up daily life. This study will explore the association between performance on various experimental tasks and day-to-day functioning. Healthy normal volunteers and patients with certain kinds of brain damage (primarily focal or degenerative lesions of the human prefrontal cortex) or psychiatric disorders may be eligible for this study. Candidates with central nervous system trauma, disease or dysfunction will be screened with a routine neurological examination and history. Participants may be asked to complete written tests, sit in front of a computer monitor and press a key to indicate a decision about what appears on the screen (for example, whether a statement is accurate) and answer questions from a test examiner. A skin conductance response (SCR) test may be done along with some of the cognitive tests. SCR uses electrodes (pieces of metal attached to wires) placed on the fingers to measure the subject's emotional reaction to a test. Participants may also do an evoked response test, in which the subject watches words or scenes on a TV screen while his or her responses are recorded from electrodes placed on the scalp (similar to an electroencephalogram). The tests will be scheduled for an average of one session a week, with each session lasting from 30 minutes to 3 hours. Generally, 15 sessions will be scheduled over a 1-year period. Special arrangements will be made to accommodate participants from out-of-town. Participants may have a magnetic resonance imaging (MRI) scan of the brain. This test uses radio waves and a strong magnetic field to picture structural and chemical changes in tissue. For the procedure, the subject lies on a table in a space enclosed by a metal cylinder (the scanner) for abou
